Answer 2

Answer:

No

Step-by-step explanation:

Here

According to Pythagoras theorem ,

Hypotenuse*2 = Base*2 + Perpendicular*2

And,

the longest side of right angled triangle is hypotenuse

So,

By Pythagoras theorem,

11*2 should be equal to sum of 5*2 and 9*2

But,

11*2 is not equal to 5*2 + 9*2

Hence, (5,9,11) is not a Pythagorean triplet.
